Embodiment
For the purpose, technical scheme and the advantage that make invention is clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Dynamic frequency spectrum deployment method of the present invention and device are fit to be applied in the network environment of multiple wireless network coexistence.Fig. 1 has shown the network environment of two kinds of wireless networks coexistences can supporting multiple different communication service.Need to prove that the present invention also can expand in the communication scenes of the wireless network coexistence that surpasses two, and can not exceed the scope that is intended to protect of the present invention.
In network environment shown in Figure 1, two kinds of employed RAT of wireless network are respectively RAT#1 and RAT#2, and these two kinds of RAT coexist in identical geographic service area, and in other words, the service coverage of these two kinds of RAT is spatially overlapped.For example, as shown in Figure 1, in the wireless coverage of the AP of RAT#1 RAT#1-AP1, also there is the AP of RAT#2, as RAT#2-AP1, the wireless coverage of RAT#2-AP2 and RAT#2-AP3.In the wireless communication system of reality, so-called AP can be a base station in the cellular network, also can be an AP among the WLAN.RAT#1-MS1 shown in Fig. 1, RAT#1-MS2, RAT#1-MS3 and RAT#1-MS4 represent to be provided by RAT#1 the MS of service, do not have to show the MS that service is provided by RAT#2 in Fig. 1.
With respect to a MS of RAT#1 service, for example for RAT#1-MS1, RAT#1-MS1 is within the wireless coverage of RAT#1-AP1, and provides service by RAT#1-AP1, and then RAT#1-AP1 is the AP services of RAT#1-MS1.In addition, RAT#1-MS1 also is within the wireless coverage of RAT#2-AP1, and therefore, RAT#2-AP1 is the coexistence cAP with described RAT#1-MS1 AP services.As shown in Figure 1, this moment, the AP services of RAT#1-MS1 was RAT#1-AP1, and the cAP of its AP services is RAT#2-AP1.And when RAT#1-MS1 moved in the wireless coverage of RAT#2-AP2, its AP services kept RAT#1-AP1 constant, and the cAP of its AP services will be changed to RAT#2-AP2.
In network environment shown in Figure 1, the spectrum requirement of RAT#1 and two RAT of RAT#2 can dynamically change in room and time because of the variation of own service amount load.In order to improve the frequency spectrum service efficiency, in dynamic frequency spectrum deployment method of the present invention, two RAT can carry out dynamically sharing to whole frequency spectrum resources, to adapt to the spectrum requirement of dynamic change.
Here, suppose frequency spectrum resource to be allocated can divide with assignable minimum unit be f, whole frequency spectrum resources of being shared by a plurality of RAT are Nf.For convenience, omit frequency spectrum minimum unit symbol f in the following description, only used N to represent whole share spectrum resources.Fig. 2 has shown the whole frequency spectrum resource N that shared by a plurality of RAT.
In order to realize frequency spectrum resource N sharing between a plurality of RAT, the preferred embodiments of the present invention have provided a kind of method of described frequency spectrum resource being carried out dynamic assignment between the RAT of a plurality of coexistences, the implementation procedure of this dynamic frequency spectrum deployment method mainly may further comprise the steps as shown in Figure 3:
A, before MS asks frequency spectrum resource that this signal post needs, this MS detects the AP services of self and the cAP of this AP services, and obtains the sign AP ID of self AP services and the sign cAP ID of described cAP.
For performing step A, need improve existing MS, that make that it can close on it detect with other AP self AP services coexistence.Those skilled in the art will appreciate that this improvement to the MS function is to realize very easily, and need not on MS, to increase complicated frequency spectrum perception technology.Specifically, for the MS of bimodulus and multimode, it can directly obtain the situation of coexistence AP among another RAT; And for the MS of single mode, it can be in the RAT of coexistence by increase a common signal channel notify portable terminal coexistence AP situation or send beacon and make portable terminal can detect the AP of coexistence.
B, described MS send the AP services of bandwidth request message to self, and carry the bandwidth demand amount of this communication in this bandwidth request message, and the cAP ID that obtains in steps A.
C, described AP services are after receiving described bandwidth request message, obtain the spectrum requirement amount of described AP services according to the bandwidth demand amount of these signal post's need that wherein carry, and send a frequency spectrum request message to the DSAM that is responsible for dynamic frequency spectrum deployment, wherein carry self AP ID and described spectrum requirement amount and cAP ID.
In this step, described AP can adopt multiple mode to send described frequency spectrum request message, and for example described AP can send a frequency spectrum request message corresponding with this bandwidth request message immediately to described DSAM after receiving a bandwidth request message; Also can be after receiving a plurality of bandwidth request message, a plurality of bandwidth request are combined, send a frequency spectrum request to described DSAM, wherein, entrained spectrum requirement amount should be the summation of the required spectrum requirement amount of described a plurality of bandwidth request in this frequency spectrum request message.A kind of implementation method in corresponding back, can determine according to predefined spectrum requirement amount thresholding the opportunity that sends the frequency spectrum request message, also can come at interval to determine, perhaps consider the time interval of spectrum requirement amount thresholding and frequency spectrum request simultaneously according to predefined frequency spectrum request time.If MS sends in the bandwidth request message of AP and further carries the type of service that MS communicates, then AP can be according to the type of service of MS communication, for example be real time business or non-real-time service, set different spectrum requirement amount thresholdings and frequency spectrum request time at interval.
The described DSAM of this step is a logic entity, and it can be an independently network equipment, also can be used as a logic module and is incorporated in the existing network equipment, for example, can be incorporated among the AP of certain wireless network RAT.In addition, the connection from the AP of certain RAT to described DSAM can be wired, also can be wireless.If described DSAM is incorporated among as shown in Figure 1 the RAT#1-AP1, the frequency spectrum request message of certain AP among the then corresponding RAT#2, can directly send to described DSAM by the AP of this RAT#2, perhaps the AP by this RAT#2 at first sends to RAT#1-AP1, and then is forwarded to described DSAM by RAT#1-AP1.
D, described DSAM are according to the spectrum requirement amount that is received, and AP ID and cAP ID carry out dynamic frequency spectrum deployment by certain dynamic frequency spectrum deployment algorithm, and the spectrum allocation may result is sent to the AP that sends described frequency spectrum request message.
E, described AP distribute the corresponding frequency spectrum resource to give described MS according to the spectrum allocation may result from described DSAM.
F, when thereby MS moves to another coexistence AP zone when causing its cAP to change, this MS need finish redistributing of relevant frequency spectrum resource.
Specifically, the described frequency spectrum resource of this step is redistributed and can be realized by carrying out step D6～D9 hereinafter shown in Figure 4.
In order to realize the described dynamic frequency spectrum deployment of above-mentioned steps D, described DSAM need set up SAT for the AP of each RAT of request frequency spectrum resource, is used to write down the spectrum allocation may situation of reality between this AP and its coexistence AP.Table 1 is the SAT example of RAT#1-AP1 shown in Figure 1.
Coexistence AP Distribute to the frequency spectrum (n1) of self Distribute to the frequency spectrum (n2) of coexistence AP
RAT#2-AP1 f1～f2 f3～f10
RAT#2-AP2 f1～f8 f9～f10
RAT#2-AP3 f1～f6 f7～f10
Other f3～f10 Do not have
Comprise one or more frequency spectrum resource assignment record among the SAT of RAT#1-AP1 shown in the table 1, wherein, corresponding one of each bar resource allocation record is shown the coexistence AP of the corresponding A P of institute with this, write down in the common coverage of this corresponding A P of table institute and its coexistence AP, for the frequency spectrum resource n1 of this AP actual allocated and be the frequency spectrum resource n2 of its AP actual allocated that coexists.By the assignment record of frequency spectrum resource shown in the table 1, DSAM can obtain RAT#1-AP1 and its coexistence AP, for example the spectrum allocation may situation of reality between RAT#2-AP1, RAT#2-AP3 and the RAT#2-AP3.
In this step, in fact DSAM carries out described dynamic frequency spectrum deployment according to described SAT and certain dynamic frequency spectrum deployment algorithm, and its concrete grammar mainly may further comprise the steps as shown in Figure 4:
D1, from the frequency spectrum request message that is received, extract spectrum requirement amount and AP ID and cAP ID;
D2, search self storage according to described AP ID, the SAT corresponding with this AP ID, if there is no corresponding with this AP ID SAT then sets up the SAT corresponding with this AP ID, and the frequency spectrum resource n1 that is made as described AP services actual allocated is 0;
D3, in the described SAT that obtains, search the frequency spectrum resource assignment record corresponding with cAP ID, if not with the corresponding record of described cAP ID, then add and the corresponding record of described cAP ID in described SAT, at this moment, the frequency spectrum resource n2 that is made as described coexistence AP actual allocated is 0;
D4, from described frequency spectrum resource assignment record, obtain to the frequency spectrum resource n1 of this MS AP services actual allocated and be the frequency spectrum resource n2 of the coexistence AP actual allocated of its AP services;
D5, according to the spectrum requirement amount r1 of the described AP services of carrying in the frequency spectrum resource request message and the spectrum requirement amount r2 of described coexistence AP;
D6, to judge whether frequency spectrum to occur congested, and whether the spectrum requirement amount r2 sum of promptly judging the spectrum requirement amount r1 of described AP services and described coexistence AP greater than whole frequency spectrum shared amount N, if, execution in step D7 then, otherwise, execution in step D8;
D7, carry out the frequency spectrum resource dynamic assignment under the congestion situation;
D8, be that described AP services is distributed the corresponding frequency spectrum resource according to the actual needs of described AP services;
D9, upgrade among the described SAT corresponding frequency spectrum resource assignment record according to the spectrum allocation may result.
Present embodiment has provided resource allocation methods under 3 kinds of congestion situations to realize above-mentioned steps D7.
Method 1: the frequency spectrum resource based on priority distributes.
Under the frequency spectrum resource allocation strategy based on priority, the frequency spectrum request with higher priority will obtain required frequency spectrum.
Wherein, priority can determine according to the RAT that initiates the frequency spectrum request simply.For example, can set the frequency spectrum request of initiating by RAT#1 and have higher priority, in this case than the frequency spectrum request of initiating by RAT#2, the spectrum requirement of RAT#1 at first is satisfied, and particularly, adopts following formula to carry out spectrum allocation may, n1=min (r1, N), n2=N-n1.
In addition, can also determine described priority according to the significance level of the business of bandwidth on demand.Wherein, the significance level of described business can therefrom be obtained income according to type of service or operator and wait divided rank.For example, voice service is because the requirement of its real-time, should be set to higher priority than data service, real time business should have higher priority than non-real-time service, and the business with high yield should have higher priority or the like than the business of low income.In the spectrum allocation may process of reality, if determine the priority of frequency spectrum request according to the type of business, then MS need further increase the type of service of communication in the bandwidth request message of steps A, and AP need send to DSAM to carry out described dynamic frequency spectrum deployment with described type of service in the frequency spectrum request message of step B.
For satisfying the bandwidth demand of higher priority service, for the current interruptable business and can not interrupted service of just can be designed as for the serviced business.If current serviced business is interruptable business, then occurring under the congested situation of frequency spectrum resource, this business can be ended, and the frequency spectrum resource of its release just can be assigned to the business that other has higher priority.And if current serviced business is can not interrupted service, after then new frequency spectrum request need be waited for current serviced service ending, could obtain the corresponding frequency spectrum resource.
From above-mentioned frequency spectrum resource allocation method based on priority as can be seen, a kind of RAT of higher priority that supports may monopolize whole available spectrum resources, to such an extent as to cause supporting that the service quality (QoS, Quality of Service) of the RAT of lower priority may be very low.
Method 2: distribute based on the frequency spectrum resource that keeps.
In based on the frequency spectrum resource allocation strategy that keeps,, be called and keep frequency spectrum resource Nrev for one or more RAT among the multiple RAT of coexistence keep certain frequency spectrum resource respectively.The frequency spectrum resource of this reservation is the amount of frequency spectrum that can guarantee to distribute to described one or several RAT when existing frequency spectrum resource congested between a plurality of RAT.In the frequency spectrum resource assigning process of reality, if it is congested frequency spectrum resource to occur, the concrete grammar that the frequency spectrum resource that keeps distributes is: the reservation frequency spectrum resource Nrev that RAT is set, the resource of the actual acquisition of this RAT is the minimum value between described reservation frequency spectrum resource Nrev and its spectrum requirement amount, and the frequency spectrum resource that other RAT that reservation frequency spectrum resource is not set can obtain is the poor of the frequency spectrum shared total resources and the frequency spectrum resource of withing a hook at the end.For example, in network environment shown in Figure 1, if when the reservation frequency spectrum of RAT#2 is Nrev2, the spectrum allocation may between two RAT of RAT#2 and RAT#1 be n2=min (r2, Nrev2), n1=N-n2.Above-mentioned frequency spectrum resource allocation method is arranged as can be seen, when the spectrum requirement amount of a RAT was no more than the frequency spectrum that keeps for this RAT, the frequency spectrum that is kept also can be shared by other RAT.
Method 3: the frequency spectrum resource based on probability distributes.
Under this strategy, when existing frequency spectrum congested, frequency spectrum resource will carry out frequency spectrum resource according to the RAT frequency spectrum resource allocation probability of predefined each coexistence and distribute.For example, in network environment shown in Figure 1, can preestablish RAT#1 and the RAT#2 spectrum allocation may probability when existing frequency spectrum congested and be respectively p1 and p2, at this moment, DSAM then can carry out frequency spectrum resource according to described spectrum allocation may probability and distribute.Wherein, p1 and p2 can determine according to criterion described below.
Said method 2 and method 3 can realize the fairness of spectrum allocation may between a plurality of RAT to a certain extent in the assigning process of frequency spectrum resource, the basic simultaneously QoS that guarantees each RAT.
By above description as can be seen, the dynamic frequency spectrum deployment method that present embodiment provides can realize sharing and dynamic frequency spectrum resource distribution of frequency spectrum resource under the situation of multiple wireless network coexistence.
In order further to simplify the described dynamic frequency spectrum deployment method of present embodiment, in another preferred embodiment of the present invention, can also distribute certain amount of frequency spectrum for the AP among the RAT of coexistence in advance.Like this, new frequency spectrum resource n1 and the n2 that adds described AP services and coexistence AP actual allocated is not 0 in step D2 and D3.
When the spectrum requirement amount of the AP among the RAT is less than or equal to pre-assigned amount of frequency spectrum, for example, when r1≤n1 or r2≤n2, RAT AP can be directly for the MS of request frequency spectrum resource distributes the corresponding frequency spectrum resource, and need not to described DSAM request frequency spectrum resource; Have only when the spectrum requirement amount of the AP among the RAT greater than for its pre-assigned amount of frequency spectrum the time, for example, when r1＞n1 or r2＞n2, the AP among the RAT just need ask the corresponding frequency spectrum resource to DSAM, and the process of request frequency spectrum resource can be referring to above-mentioned steps A～E.Can reduce the signaling traffic load of spectrum allocation may by the frequency spectrum resource assigning process of such preferred embodiment realization.

The cumulative distribution function of representing frequency spectrum resource demand variable r below with F (r), and further define frequency spectrum overload probability (SOP, probability when Spectrum Outage Probability) G (n) is for the amount of frequency spectrum n that surpassed reality as spectrum requirement amount r and distributed, its concrete computing formula is as follows:
G ( n ) = Pr ( r > n ) = ∫ n ∞ f ( r ) dr = 1 - F ( n )
In Fig. 6, SOP G (n) is shown as below curve f (r) simultaneously again the shadow region in spectrum allocation may vertical line n right side part.Defined SOP can be used to measure the QoS that RAT can provide from the angle of frequency spectrum.Defined frequency spectrum overload probability SOP provides the mode of more generally measuring than traditional grade of service (GOS, Gradeof Service) under the professional situation about existing of several data.
The SOP value of representing two RAT with Gi (i=1,2) respectively.For the described method 2 of above-mentioned steps D9, Gi is the predefined function that keeps frequency spectrum resource Nrev1, Nrev2 for RAT.For the described method 3 of above-mentioned steps D9, Gi is that the RAT of predefined coexistence is at the function that has the congested time-frequency spectrum resource allocation of frequency spectrum Probability p 1, p2.

Wherein, represent can be from two whole incomes that RAT obtained for R.Therefore, this criterion is only considered from the angle of wireless carriers income.For the described method 2 of above-mentioned steps D9, R is the predefined function that keeps frequency spectrum resource Nrev1 and Nrev2 for RAT.For the described method 3 of D9, R is that the RAT of predefined coexistence is at the function that has the congested time-frequency spectrum resource allocation of frequency spectrum Probability p 1 and p2.
Criterion II:Gi≤δ i, (0＜δ i≤ 1) i=1,2.
Wherein, Gi is expressed as the SOP value of two RAT, δ respectively iBe expressed as the SOP threshold value that two RAT are provided with respectively, therefore, the QoS that this criterion only can provide from two RAT considers.
Criterion III: satisfy maxR and Gi≤δ i simultaneously, (0＜δ i≤ 1) i=1,2.
This criterion has been considered the income of wireless carriers and the QoS that each RAT can provide in fact simultaneously, obtains certain balance at running income with the QoS that provides.
Criterion IV: satisfy Gi≤δ i simultaneously, (0＜δ i≤ 1) i=1,2 and R 〉=α Rmax (0＜α≤1).Wherein, Rmax is illustrated in the resulting maximum value of wireless carriers under the criterion I condition, and α is predefined coefficient.This criterion has in fact also been considered the income of wireless carriers and the QoS that each RAT can provide simultaneously, also can obtain certain balance at running income and the QoS that provides.
